Yes, it might make sense although embedded wants to disable CONFIG_BUG
on systems which cannot report errors:
│ CONFIG_BUG:
│
│ Disabling this option eliminates support for BUG and WARN, reducing

│ numerous fatal conditions. You should only consider disabling this
│ option for embedded systems with no facilities for reporting errors.
